我的公钥名为lagotto_rsa.pub，这就是它应该默认使用的那一个，但现在它似乎无法找到的公共密钥。

ssh -i ~/.ssh/lagotto_rsa.pub [email protected] -v

给我也Permission denied (publickey).

我也用私钥试了一下。我想知道我的本地机器发生了什么变化，我无法访问远程了

你的问题是[离线]（http://stackoverflow.com/help/on-topic）在这里。 –

这不是你的远程，但你的服务器有问题。只有当您在后端更改权限时才会发生此错误。这是一个真正令人讨厌的错误，我只能解决它，因为我的网站托管在数字海洋上，并且它们可以让您访问控制台。所以这是唯一可能的，因为这一点。客户端无法做到这一点。如果可以的话，我问了一个关于这个问题的问题。否则让我知道

[链接]（http://askubuntu.com/questions/698101/ssh-exchange-identification-read-connection-reset-by-peer-error）仔细阅读评论部分，你会发现你的答案 –

谢谢我将检查AWS是否有控制台访问，如DO –

很高兴我可以帮助:) –

如果您可以任何其他方式连接到您的服务器，请检查~/.ssh/文件夹和~/ssh/authorized_keys文件的权限。它们应分别设置为700和600。

您还可以检查/var/log/auth.log文件以查看尝试登录时会发生什么。如果您的系统有systemd，您可以通过sudo journalctl -u sshd或sudo journalctl获取更多信息。

奇怪在我的本地我没有'authorized_keys'。 'chmod：can not access'。〜/ ssh/authorized_keys'：没有这样的文件或目录' –

我正在谈论的'authorized_keys'文件位于你的服务器上，而不是你的本地机器上。 – jeremija

好的谢谢...晚上会很长:)我必须找到一种方法来访问它 –
